“…These results confirm previous data obtained by Oda et al (2000), who studied the effect of different rootstocks on tomatoes in which the growth of scions was depressed and where stems at the graft union thickened markedly 18 weeks after grafting. In contrast, another study (Oda et al, 2005) indicated that little or no effect of rootstocks species appeared on the growth of tomato plants scions except for an increase of stem thickening at the graft union. In our results, stem diameter increased in scions grafted on S. torvum and on the double graft, which is a characteristic of graft incompatibility associated with a poor connection of vascular bundles between rootstock and scion (Oda et al, 1996).…”

“…It may also decrease the stem diameter of the rootstock, which may result in poor root system development (Oda et al, 1996) and, therefore, in lower hydraulic conductance. The latter consequently reduces nutrient transport to the leaves, which become yellow, and leads to low yield and to the production of smaller or of bad quality fruits and, eventually, to the premature death of the plant (Fachinello et al, 1995;Fernández-García et al, 2004;Oda et al, 2005).…”

2 Two tomato scions (cvs. 'Raf' and 'Gorety') were grafted on three different rootstocks: S. torvum, 'Beaufort' (Lycopersicum esculentum × Lycopersicum hirsutum) and intermediate grafting of eggplant 'Cristal' between tomato and S. torvum (double graft). Plants were grown in Mediterranean greenhouse conditions. The response to grafting was measured through growth parameters, F v /F m and leaf macronutrients analysis, and it was compared with non-grafted plants. The scions grafted on S. torvum in simple and double graft showed lower fresh and dry weight of leaves, number of commercial fruits, plant height, F v /F m and decreased their capacity to absorb several nutrients resulting in a lower mineral concentration in scions leaves, as a result of a thickened graft union. On the other hand, both scions showed a good response when grafted on the rootstock 'Beaufort', with which growth parameters, yield and photosynthetic capacity were similar to non-grafted plants.

“…Thus, the root surface area and root permeability in grafted plants may be affected by the scion cultivar. To elucidate the reasons for the difference in fresh weight of the aerial part between the sympatric combinations (Figure 3) and the absence of such difference between the allopatric combinations (Figure 4) in our study, we need to investigate grafting compatibility [16] [38], hydraulic resistance of xylem vessels [39], or other physiological factors. …”

Grafting is widely established in agriculture and provides practical advantages for vegetable production. We investigated physiological differences between the grafted combinations of Dutch (Starbuck and Maxifort) and Japanese (Reiyo, Receive and Magnet) tomato cultivars. Plants were grown hydroponically until the flowers on the first truss bloomed, and the following parameters were measured: fresh weight of the aerial parts, root surface area, root permeability (by using a pressure chamber), and water potential of exudates (by using an isopiestic psychrometer). The Starbuck/Maxifort combination had higher values of the aerial part weight, root surface area, and root permeability than Reiyo/Receive, whereas Reiyo/Maxifort tended to have higher values of these parameters than Reiyo/Receive and Reiyo/Magnet. Maxifort had a significantly larger root surface area than Receive, but root permeability was not significantly different. InReiyo/Maxifort and Starbuck/Receive, these parameters were not significantly different except for a single comparison of root permeability. Thus, root permeability and root surface area may depend not only on the rootstock but be also affected by scion in grafted plants. Water potential of exudates was similar in most combinations and experiments. This shows that three rootstock cultivars provided similar nutrient concentrations even with different scions.

“…The overall result is that the uptake power of the plant is disminished (Kramer and Boyer 1995). During the formation of the graft union, the vascular connection in the rootstock-scion interface may determine water and nutrient translocation, affecting other physiological traits (Oda et al 2005;Johkan et al 2009). However, water and nutrient uptake could be increased in grafted plants as result of the enhancement of vigour by the rootstock root system and its effects on plant yield (Ruiz et al 1997).…”

The response of grafted vegetables to stress conditions owing to the nutrient status may be different than that of self-rooted plants, depending mainly on the rootstock genotype. The aim of the present work is to determine the response of reciprocal grafts made between cherry tomato cultivars (Solanum lycopersicum) to moderate water stress, examining uptake and concentration of nutrient. The tomato cultivars Zarina (drought-tolerant) and Josefina (drought-sensitive) were reciprocal grafted and selfgrafted, and ungrafted were used as control. The total content and uptake fluxes of macro-and micronutrients were determined in leaves. Our results show that the use of drought-tolerant cv. Zarina like rootstocks (ZarxJos) showed improve ionome, with increases in nitrogen (N), phosphorus (P) and potassium (K) concentration and uptake fluxes, and an increase in iron (Fe) and copper (Cu) concentration and uptake under water stress. Besides, the vigorous root system of rootstocks is often capable of absorbing plant nutrients more efficently than scion root, and we have showed that cv. Zarina and ZarxJos develop a better radicular system. This result confirms the hypothesis that grafted plants on vigorous rootstocks can improve mineral nutrition and nutrient uptake with respect to ungrafted plants, especially under water stress conditions.
